Abstract (en)
A feed injector (30) for a fluid catalytic cracking reaction zone, which provides improved oil atomization and dispersion comprises a straight-pass conduit section (31), in which a feed oil and steam are pre-mixed, and a terminal section (35), where the oil is atomized and dispersed by a generally fan-shaped distributor (39). The feed injector (30) produces a substantially flat spray pattern across the direction of catalyst flow in the catalyst/oil contacting section of the catalytic cracking reaction zone. Improved product yield and lower coke and light gas yields are obtained. <IMAGE>
